There are different levels of moderators and support found on Twitch and Twitch's social media. To avoid confusion, here is a list ranging from users to staff. No other labels are officially sanctioned as Twitch support, staff, or volunteers unless stated here.
Twitch Staff: These are the fine folk who make Twitch tick. Say hello!
Admins: Paid personnel who review grief reports and enforce our Terms of Service. In short, they help us keep Twitch safe and fun.
Global Moderators: A Global Moderator is basically a Super Channel Moderator: all the privileges of a Channel Moderator across all channels on the site. Global Moderators are volunteers who have extensive experience and knowledge of all things Twitch. They're here to help!
Broadcasters: This is the owner of the channel that you are currently visiting on Twitch. Broadcasters have the ability to enforce chat rules for their channel and appoint/remove channel moderators.
Chat Moderator: A member with this icon is a moderator of the channel you're currently visiting. They are selected by the channel owner and have the ability to time out, ban, and enable slow or subscriber-only mode in this chat.
Turbo User: A subscriber of Twitch's monthly premium user service. More information can be found here
During your time interacting with chats on Twitch you will notice emoticons, there are thousands to be discovered that include global emotions and subscriber emotions that you can unlock by subscribing to a streamer!
Emotions play a heavy role in the Twitch culture and we encourage you to join in.
